The Additional <HEAD> Content feature allows webmasters to insert additional Meta tags, HTML, or code for other scripts into the header of a web page. Often times scripts, like javascript, have code that needs to be in the header of a page as well as code that needs to be in the body of the page. Use the Additional <HEAD> Content feature to insert the necessary code into the header of the page.
*Warning: The Additional <HEAD> Content feature is an advanced feature which should only be used by those experienced in HTML and other scripts. Entering the wrong thing into the Additional <HEAD> Content box can have unexpected and serious side effects on the web page.
